    摘要: A method of determining a physical property of a substrate includes recording a first spectrum obtained from a substrate, the first spectrum being obtained during a polishing process that alters a physical property of the substrate. The method includes identifying, in a database, at least one of several previously recorded spectra that is similar to the recorded first spectrum. Each of the spectra in the database has a physical property value associated therewith. The method includes generating a signal indicating that a first value of the physical property is associated with the first spectrum, the first value being determined using the physical property value associated with the identified previously recorded spectrum in the database. A system for determining a physical property of a substrate includes a polishing machine, an endpoint determining module, and a database.

    摘要: A method of forming bare silicon substrates is described. A bare silicon substrate is measured, wherein measuring is performed by a non-contact capacitance measurement device to obtain a signal at a point on the substrate. The signal or a thickness indicated by the signal is communicated to a controller. An adjusted polishing parameter according to the signal or thickness indicated by the signal is determined. After determining an adjusted polishing parameter, the bare silicon substrate is polished on a polisher using the adjusted polishing parameter.

    摘要: Systems and methods for performing one or more measurements of a substrate at one or more radii along the substrate are described. Thickness measurements taken at various radii along the substrate can be averaged together to obtain an average value that reflects an overall substrate thickness. A more accurate measurement of the overall substrate thickness can be obtained by performing multiple measurements and averaging the measurements together. Using the average value, polishing can be adjusted to ensure that the substrate achieves a desired planarized thickness profile.
